SUBMERGED METALLIC PUIVIP.

SPEGIFICATION forming part of Letters Patent No. 438,163, dated October14, 1890. Application led July '7, 1890. Serial No. 357,987. (No model.)

To a/ZZ whom it may concern.-

Beit known that I, GEORGE J. KELLER, a citizen of the United States,residing at Osceola, in the county of Polk and State of Nebraska, haveinvented certain new and useful Improvements in Submerged MetallicPumps; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art t0 which it appertains to make and use the same.

The invention relates to submerged metallic lift-pumps, and the specialobject of the invention is to improve the pump patented to me December3l, 1889, by taking in and lifting a large quantity of water with a veryshort stroke of the piston-rod, whereby a very short lever or handlewill be required between the standard and piston-rod.

Figure l of the drawings is a vertical diametrical section of mysubmerged pump, and Fig. 2 a top plan view.

In the drawings, A represents the pumpcylinder having a top cover E,fitting an external rabbet and secured by the screws t), while thebottom thereof is open. The cylinder A is divided into compartments A bythe radial partitions m and the horizontal partitions n. In eachcompartment is a piston hinged at g, and having a valve hinged theretoat g. The piston G is open at g2, and this opening is covered by thevalve when closed. At the under side of the back of each piston isfastened one end of a rod g3, while from the front extends down the rodgft to connect with it. The end of the rod g3 is connected by a pivotedrod II with the piston-rod I. J is the water-inletin which works the endof rod g3 and the rod II. The cylinder is :made with a concave n',corresponding to the arc in which the piston moves. It will thus beperceived that each piston moves but a short distance to lift the waterand compel it to pass through the outlet o.

B represents a central discharge-pipe divided so as to make a separatepipe b for each vertical row of compartments A and opening at o intoeach compartment. Over the upper open end of each sub-pipe l) is locateda hinged valve b', which the upward pressure of water opens, while theyclose by their own gravity, the suction caused by the downward movementof the piston and also by the pressure of the superincumbent water. Thebottom of the pipe B is closed by a screw-cap D. Two opposite verticalrows of compartments have pistons which move in opposite directions, sothat the water from one-half the compartments A is passing into thechamber K while the pistons in the other chambers are moving down totake water for the nextlift. In this way a constant stream of water willbe flowing up through the delivery-pipe L.

The piston-rods I may be operated by any suitable mechanism and by anypreferred power.

Of course I do not confine myself to any particular number ofcompartments A', and may use anysuitable packing for the pistons andvalves.

F represents a frame connected With the bottom of the cylinder by thescrewst to support it on the bottom of the well, while p are guides forthe piston-rods. The pipe B may be central or at one side.

Having thus described all that is necessary to a full understanding ofmyinvention,what I claim as new, and desire to protect by LettersPatent, is-

l. In submerged pumps, a topcl0sed and bottom-open cylinder divided byvertical and horizontal partitions into vertical rows of compartmentsA', each provided with a hinged piston having an upwardly-opening valve,in combination with avertical pipe divided vertically and arrangedcentrally or otherwise, each sub-pipe Z9 connecting by an opening o"with each compartment in a vertical row and having at the top anupwardlyopening valve, whereby each piston moves a very short distance,but all co-operate to fill one receiving-chamber K, as set forth.

2. The combination, with the straight piston-rod I and the pistons G,arranged one above another in chambers A', of the rods g3 g4 and the rodH, the latter pivoted to the rods I g4, as and for the purpose setforth.

In testimony whereof I affix my signature in presence of two witnesses.

. GEORGE J. KELLER.
